Phatch – photo batch processor and Exif renamer

PHoto bATCH Processor (Phatch) is a simple to use open source GUI Photo Batch Processor which handles all popular image formats and can duplicate (sub)folder hierarchies.

Phatch can batch resize, rotate, apply perspective, shadows, rounded corners, … and more. Phatch allows you to use EXIF and IPTC tags for renaming and data stamping. Phatch also supports a console version to batch photos on webservers.

Phatch is a cross-platform tool, running on Linux, Windows and Mac operating systems.
